DIT Hothouse posted this:iSeal: Advanced Surface Treatment for Protection against TribocorrosionThis invention is based on the application of a hybrid organic/inorganic treatment onto an exposed surface – either as a stand-alone treatment or as a sealant. The treatment is applied using an electrochemical deposition technique, allowing for the development of conformal coatings, irrespective of design complexity. Layer thicknesses are low (10-100nm) but resistance in corrosive marine environments indicate corrosion rates comparable to technologies currently employed by the aerospace and automotive industries. Corrosion rates are reduced by between 103 and 105 times, dependant on the nature of the porous coating. Tests on metallic coatings indicated a reduction in corrosion rates of approximately 103-104 while tests on ceramic coatings indicated a reduction in corrosion rates of approximately 105. By applying the hybrid treatment as a sealant treatment onto a porous wear resistant coating, concerns regarding the effect of mechanical damage are dramatically reduced. In addition, surface roughness levels are similar to electropolished finishes.

Universidad de Alcalá-OTRI posted this:Portable device to measure the displacement maps on surfaces in the three spatial directionsA Spanish research group from the Department of Signal Theory and Communications of the University of Alcalá along with a Spanish research group from the Department of Mechanical and Mining Engineering of the University of Jaén has developed a portable optoelectronic device to measure the displacement of each surface element in an object when is subjected to deformation. In particular, the device allows obtaining maps of long range displacement (greater than mm) in dynamic regime (in real time). Thus this system is very useful in the experimental study of the materials’ mechanical properties, especially if they suffer large deformations at high speed. It is a computationally simpler alternative and more inexpensive than the digital mapping technique for 3D images which is currently the only one allowing such measures. The group seeks licensing agreements, collaborative and commercial agreements with technical assistance.

UNIVERSIDAD DE ALICANTE posted this:Energy absorbing device in motor vehicle collisionsResearchers at the University of Alicante have devised a system to partially absorb the energy generated in a crash involving at least one motor vehicle traveling at a high or medium speed. It is a passive protection system for vehicles which absorbs the maximum amount of mechanical energy in a crash with minimal added weight and volume. Assumes additional protection that enhances the vehicle's passive safety, minimizing the consequences of a collision for the passengers. The system has an innovative design that allows placing it in different positions inside the vehicle or making structural parts and is manufactured with advanced materials. Innovative aspects The system is designed to provide protection that goes beyond the current regulations for passenger cars, as it is able to absorb a larger proportion of the mechanical energy generated in a collision. Also improve the passive safety of vehicles (vans, trucks) or special vehicles (ambulances, fire trucks, armored vehicles) in circulation. It also provides substantial improvements for heavy duty vehicles, contrary to what is happening now should be able to absorb themselves much of the energy produced in a collision with a vehicle lighter, thereby minimizing the potential damage that may occur in people who travel light vehicle. The system consists in several stages which act consecutively on impact, absorbing energy in a gradual and proportional to the energy generated in the collision, which is a lower acceleration on passengers, thereby reducing the potential injuries. Less weight, volume and system size compared to traditional structural systems, through the use of advanced materials: tensile filaments that act in case of collision, thermosets broken links which act by absorbing the impact energy generated in the fiber and combined with high strength composite metal / polymer composite micro / nanostructures
